Either at the driving range or on the course when practicing.
Driving Range (5 balls with each wedge)
Make five swings with each wedge while wearing our FLYT sleeve. The max length of your back swing will be about waist high or a little further. Accelerate into a comfortable finish position. Hit 5 balls with each wedge to figure out how far the ball is carrying. Knowing these max carry yardages will really help you improve and make your life easier this spring!
One the course at two or three different times throughout your round, take 3 balls and hit one max length swing with each wedge. Record the yardages and find the average for each wedge at the end of your round.
